Constructed wetlands for costeffective and energy-efficient remediation of pl...Frank Pels
In the Netherlands, often only contaminated source locations are remediated, while pollution plumes keep growing as natural conditions do not always support natural (bio) degradation. Gradually, large areas will be (lightly) polluted. Traditional approaches of remediating those plumes are very costly and will cause a lot of CO2-emissions. With an alternative nature-based approach, plume remediation can be achieved in a cost-effective and energy-efficient way, by using constructed wetlands. Such biological groundwater treatment plants could be situated in green public areas. In three cases, results and costs of the implementation of constructed wetlands will be presented. With these project examples we will show that this application is a promising sustainable way of future plume remediation, which can be incorporated in urban groundwater management and other schemes of sustainable land management and land stewardship. The three case studies are briefly introduced below and will be further elucidated in final abstract and presentation.
This document discusses water and moisture in the atmosphere. It covers the global distribution of water, properties of water including its phases and heat properties. It also discusses concepts of humidity including relative humidity and specific humidity. Atmospheric stability is influenced by environmental and adiabatic lapse rates. Clouds and fog form when rising air parcels become saturated.
The document describes the design, fabrication, and performance evaluation of a waste heat driven desiccant dehumidifier. It contains silica gel as the absorbent material. The dehumidifier operates in absorption and regeneration cycles. In absorption, moist air passes through the silica gel beds which absorb moisture. In regeneration, hot air is passed through to release the absorbed moisture and regenerate the silica gel. Experimental results show the dehumidifier can reduce humidity by 5-10 grams of moisture per kilogram of dry air over approximately 10 minutes of absorption before leveling off. The start-up period for regeneration is around 12 minutes to fully dry the silica gel.
The document discusses the water cycle and different states of water in the atmosphere. It describes key water and atmospheric concepts like relative humidity, dew point, clouds, precipitation, and different types of clouds and precipitation. The main topics covered are the water cycle, states of water as ice, liquid, and vapor in the atmosphere, how temperature and humidity are related, what causes clouds and precipitation to form, and different classifications of clouds and precipitation.
The atmosphere is composed primarily of nitrogen and oxygen. It also contains water vapor, ozone, and particulates. Atmospheric pressure decreases with increasing altitude and is measured with a barometer. The layers of the atmosphere include the troposphere closest to Earth where weather occurs, the stratosphere containing most ozone, the mesosphere being the coldest, and the thermosphere where temperatures increase with altitude. Solar radiation enters the atmosphere and is scattered, reflected, absorbed, and contributes to the greenhouse effect, while heat is transferred through conduction and convection.

A Literature Review On Extraction Of Potable Water From Atmospheric Air Using...Elizabeth Williams
This document is a literature review on extracting potable water from atmospheric air using solar stills. It discusses how solar energy can be used to condense water from air and discusses efforts to increase the efficiency of this process using various absorbents and solar still designs. The review evaluates the effectiveness of different studies and factors like temperature, humidity, and solar radiation that affect the process. It concludes that certain desiccants like calcium chloride and silica gel can be effectively used in solar still designs to extract potable water from air. High air temperatures that cause water scarcity can be overcome by utilizing solar energy.
Cyprus relies heavily on desalination plants for its water supply due to decreasing rainfall and frequent droughts. Two major desalination plants were constructed in Larnaca and Dhekelia in 1997 and 2001 respectively, which now provide over 90% of the water supply to Nicosia, Larnaca and Famagusta. Additional plants are planned for Limassol and Paphos. While desalination has significantly increased water availability, it requires large amounts of energy and results in increased air pollution, posing environmental challenges.
Dams can have significant ecological impacts:
1) They obstruct fish migration and disrupt populations.
2) Water quality is reduced as still water gathers pollution and alters temperatures affecting oxygen and chemical reactions.
3) Sediment builds up behind dams, raising water levels and putting pressure on dam walls which could eventually burst, flooding towns.
An Experimental Study on a New Design of Double Slope Solar Still with Extern...IOSR Journals
The world demand for potable water is increasing steadily with growing population. Desalination using solar energy is suitable for potable water production from brackish and seawater. In this paper, we presents design, fabrication and testing of double slope solar still with external flatted and internal parabolic reflectors and also optimization of external flat reflector tilt angle for Egyptian climatic conditions. The external flat reflector tilted at (30°, 45°, 60° and 75°) on the horizontal plane. The depth of water inside basin still is 1cm. Experimental results were compared with conventional double slope solar still. Optimum tilt angle is found to be 60° with a maximum daily productivity of 9.89 lit/m2.
Desalination Approach of Seawater and Brackish Water by Coconut Shell Activat...ijtsrd
"Engineers are challenged to develop cost effective ways to produce large quantities of water suitable for drinking, crop irrigation and commercial use for regions of the world that suffer from water shortages. Water desalination is expensive, requiring large amounts of energy and specialized equipment to convert saltwater into drinking water. The present study aims to develop a cheaper, cleaner, easy and more energy efficient way of desalinating seawater technique by using natural filters, it can help the common people as it affordable during their immediate requirements. The developed technique seemed to be very effective in reducing the concentration of seawater ions. The desalination system is developed by selecting coconut shell charcoal as the substrate material. As per the results obtained from prototype of seawater and brackish water, there is 60 reduction in chloride and 75 reduction in sodium this is mainly due to the usage of activated carbon charcoal as the filter media. It is also observed through experiments that there is 100 reduction in iron,53 reduction in sulphate, 20 reduction in total dissolved solids and 12 reduction in hardness which clearly indicates that the selected filter medias those are activated carbon charcoal, sand, laterite would be used as the filter medias for future experiments on desalination using natural filters.This work is to present an overview of current and future technologies applied to the desalination of brackish as well as seawater to produce freshwater for supplementing drinking water supplies to the common people in smaller quantity. Removal efficiency increases with the increase in contact time respectively, for both seawater and brackish water, which was considered to be maximum purification ~40 .

It was found that solar distillation effectively removes contaminants and microbes from feed water.
Review on Hydrodynamic Modelling of Desalination Plants Brine Effluent Marine...IJAEMSJORNAL
This document provides a review of hydrodynamic modeling of brine effluent from desalination plants discharged into the marine environment through outfalls. It discusses several past studies that have modeled brine dispersion using software like CORMIX and numerical models. Key findings from the studies include that dilution of brine to 1 ppt or lower within a reasonable distance is needed to limit environmental impacts. Outfall design aspects like inclination angle, discharge velocity, and use of single versus multi-port diffusers can influence initial dilution and dispersion of the brine plume. Tidal currents may cause brine plumes to oscillate and temporarily return to the outfall location, increasing local salinity. More data and unified approaches are still

How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

- Southern Italy, Spain and other
The deficit of fresh water
resources is one of
mankind global problems
3. 3
There are areas where it is
sorely lacking clean drinking water on the
planet. Women of some African tribes
must dig wet sand for many days seeking
for brown liquid, scooping it by spoons.
Only one-two liters of dirty water is
accumulated per day.
There are only a rainwater and
a coconut milk for quenching thirst in
islands of south seas. Often children are
not allowed to play active games because
the child will be sweating and thirst will
be more.
Fresh water is an important economic and social factor. The
lack of drinking water can lead to starvation, disease, political instability
and military conflicts.

Structure of drinking water production by
desalination:
Disadvantages of desalination:
- the formation of highly concentrated salt solution
affecting the environment in the production
process,
- High power consumption.
At a time there are 13-14 thousand km3 of water in vapor form (for comparison, in the
rivers about 2 thousand km3) are contained in the atmosphere. Annually from the surface
of seas and oceans nearly 0,35 – 0,5 million km3 of moisture is evaporated.
Obtaining fresh water by condensing it from the air does not lead
to environmental pollution.
5. The technical solution consists in lowering the
temperature of dew point, by compressing the saturated
atmospheric air. The extracting is made from moisture
condensers cooled by sea water.
Saturation of atmospheric air with moisture is
carried out by additional heating of sea water using the
radiant energy of the sun and of recovering thermal
energy of compressed air.
Compression of moisture saturated atmospheric
air is produced by volumetric actions compressors with
actuator driven by renewable energy of sea waves.
